### node-canvas-webgl example
|
||
|
|
|
||
|
|
#### screenshot.js
|
||
|
|
Generates Screenshots of the bot world
|
||
|
|
|
||
|
|
### Starting
|
||
|
|
|
||
|
|
Linux:
|
||
|
|
|
||
|
|
`
|
||
|
|
xvfb-run -s "-ac -screen 0 1280x1024x24" node <your script> [...args]
|
||
|
|
`
|
||
|
|
|
||
|
|
Mac High Sierra:
|
||
|
|
|
||
|
|
`node <your script> [...args]`
|
||
|
|
|
||
|
|
### Installation:
|
||
|
|
Installation on a none unix based systems is none trivial.
|
||
|
|
I suggest you install it on something like Ubuntu. Or a Virtual Machine running Ubuntu.
|
||
|
|
Mac OS X may work too, but I have only tested it on 10.13 High Sierra.
|
||
|
|
|
||
|
|
Do `npm install` to install all required node packages.
|
||
|
|
|
||
|
|
#### Troubleshooting (Linux):
|
||
|
|
If npm fails while installing try installing the following and try again:
|
||
|
|
```bash
|
||
|
|
sudo apt-get update -y
|
||
|
|
sudo apt-get install -y xserver-xorg-dev libxi-dev xserver-xorg-dev libxext-dev xvfb
|
||
|
|
```
|
||
|
|
|
||
|
|
### Docker
|
||
|
|
If you want to run the screenshot example on windows without a vm you can install it in a Docker Container.
|
||
|
|
|
||
|
|
Building the Docker image:
|
||
|
|
```bash
|
||
|
|
cd screenshot-with-node-canvas
|
||
|
|
docker build . -t screenshot-bot
|
||
|
|
```
|
||
|
|
|
||
|
|
Running the image and saving the screenshot to the current directory:
|
||
|
|
```bash
|
||
|
|
docker run -v $(pwd):/usr/src/app/screenshots -e HOST='<server ip address>' -e PORT=<port> screenshot-bot
|
||
|
|
```
|
||
|
|
`-e USERNAME=User1` and `-e PASSWORD=<Your password>` can be added if the server is not running in offline mode.
